Hi and welcome to the forum! Your bottle dates to the 1970s or 80s. Value I'm afraid is minimal, maybe $5 at most. To get the exact date it was made, look at the number that's to the right of the D in a diamond. That's the last digit of the year of manufacture.

Oh yeah that's a good point about the D in a diamond, those were mostly phased out by 1979. I don't know about 1969 though, because it has a screw top. I don't think they were using those in 1969. And the SHA also does note that the D in a diamond continued to be used up to 1979 on a few bottles https://sha.org/assets/documents/Som...%20English.pdf
Atd001, does it have Metric contents listed on the English side of the bottle?

Yeah, you're right. I don't see any metric on there, but maybe the OP can confirm that.

Looking at the base of bottle again, I see the following symbol to the left of the diamond: |_|

Dominion used a combination of lines as date codes in the 1950's and 1960's. According to SHA, this was last used in 1969. We've determined this bottle is quite late, so that rules out 1959, so the evidence points to it being an early screw top from 1969.

It's possible the SHA site is wrong and the line codes were used later, but I don't have any 1970's bottles handy to check.

I think you misread on the date codes, that's the progressive box system which was used much later than 1969. The SHA system states that it was still in use when it was published in 1986. But, I just noticed that the other side of the bottle is shown in that last image, and there's no metric labeling, which suggests you're right about it being 1969. That's really surprising to me, I didn't think that sort of modern screw top cap was used anywhere near that long ago. So OP, while your bottle probably still isn't worth much, it looks like it is more interesting than I initially thought.
